Can you solve physics problems?
Can you solve physics problems? Multiply and divide the quantities until the units match the units of the answer quantity. For example, if you’re trying to find Potential Energy (kg*m2/s2) and you have the height (m), mass (kg) and gravitational acceleration (m/s2), you can match the units by multiplying the three quantities (m*kg*m/s2=kg*m2/s2). How do […]

Does changing current affect voltage?
Does changing current affect voltage? To answer this question, the relationship between the voltage and current variables given must be specified. and thus that the current will change proportionally with the voltage. and thus the current will change exponentially with the voltage. Does higher voltage draw less current? If the voltage out is twice that […]
